abstract background and objective: proficiency testing schemes as a part of quality system in clinical and research laboratory centers provides the opportunity to evaluate the quality of test results. in this paper, we try to introduce the proficiency testing schemes as a useful method for achieving standardization and homogenization of test results in clinical and research laboratory centers. ...

the aim of this study was to evaluate the utility of a proficiency testing program among limited number of local laboratories as an alternative to the iupac/citac guide on proficiency testing with a limited number of participants, specially where international schemes are not accessible. as a sample scheme we planned to determine aflatoxins (b1, g1, b2, g2, total) in iranian pistachio matrix. a...

Environmental DNA (eDNA) monitoring has revolutionized the way biodiversity is surveyed and been proposed as a reliable method to inform management decisions. Recognition of eDNA techniques tools biosecurity require stringent standards assess sample quality reliability results. Laboratories can have their workflows assessed certified through accreditation be involved in proficiency testing sche...

Leaders Is the proficiency test in cervical cytology proficient? It is accepted that internal quality control and external quality assurance are necessary elements in ensuring high standards in the reporting of cervical smears. A major component of external quality assurance in the United Kingdom in recent years has been the proficiency test in cervical cytology. Participation in regional profi...

Performance in proficiency testing (PT) schemes is an objective measure of a laboratory's best performance. We examined the performance of participants in two parasitology PT schemes in South Africa from 2004 through 2010. The average rates of acceptable scores over the period were 58% and 66% for the stool and blood parasite schemes, respectively. In our setting, participation in PT alone is i...
